!ArcFS/!Help
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

!Help file for ArcFS version 0.65
by M.Smith
29th January 1994
The current full version is v2.23 - Details of how to get it are in the info
box.
Full information on ArcFS is available as part of the 'ArcFSExtra' package,
along with technical documentation and utilities.
This version of ArcFS is not P.D., but may be distributed subject to the
conditions in the 'Licence' file.
ArcFS has filing system number 56. My thanks to Acorn for the allocation of
this filing system number and for the allocation of the SWI chunk base
(&437C0) and Filetype (&3FB).
ArcFS allows the loading and opening of (compressed) files in archives as
easily as files on ADFS or RamFS. It has its own ArcFS filer which displays
the root directory in a filer window of any archive which is double
clicked. From then on files and applications may be loaded as normal by
double clicking them. Directories may be displayed also by double clicking
them. ArcFS can, of cause, also be used from the command line. Facilities
for loading encrypted files are included, via a preferences window which can
be obtained by clicking on the ArcFS icon. An option to display the
hourglass whilst ArcFS is working is also provided
The performance of ArcFS depends on many variables such as the machine you
are using and the media (hard disc, floppy, network etc.). Loading from
floppies should be as fast or faster than loading the same material,
uncompressed. Loading from hard disc will usually be slightly slower when
using compressed data.
*New to v0.60 / v2.20*
Now *MUCH* Faster. Support for a new archive filetype (&3FB) so ArcFS
archive aren't loaded by SparkFS. Full version also now puts a second copy
of file catalogue information immediately before the file data to make
recovery of files from corrupt archives easier.
*New to v0.65 / v2.23*
Memory mangement has now been separated out into another module. In time,
this will allow for memory other than RMA to be used as workspace.
